Drawings

Fig. 1 is a schematic view of a first embodiment of the present invention.

Fig. 2 is a schematic diagram of a second embodiment of the present invention.

Fig. 3 is a schematic diagram of a third embodiment of the present invention.

The device comprises a discharge opening 3, a roller 1, a magnetic mechanism 2, a scraping blade 4, a conveying belt 7, a chute 5, a collecting tank 6 and a screen 31.

Detailed Description

The present invention will be described in detail with reference to the following embodiments and drawings.

The first embodiment is as follows:

as shown in fig. 1, a deironing machine for lithium manganate powder comprises a material leakage port 3, a roller 1, a magnetic mechanism 2 arranged in the roller, a scraping blade 4 arranged at one side of the roller, a conveyer belt 7 arranged at the lower side of the roller, a chute 5 arranged below the scraping blade and a collecting tank 6; the magnetic means 2 are located inside the drum, occupying a certain area around the drum, while on the side where the doctor blades 4 are arranged, corresponding to the inside, the magnetic means 2 are not arranged, and the discharge opening 3 is located on the upper side of the drum 1.

Specifically, the screen 31 is arranged in the material leakage opening 3, and the material leakage opening 3 is in a shaking state during operation, so that a plurality of mechanisms for realizing the shaking state are provided, for example, an eccentric shaft, an inclined rod and the like are adopted, which are not shown in the embodiment, and the powder is scattered and falls on the surface of the roller 1, especially, the height difference is small, so that the powder can better contact with the roller 1.

Specifically, magnetic mechanism 2 is the permanent magnet that produces the magnetic field, for example magnet, and its arrangement form encircles inside the cylinder, as shown in fig. 1, the utility model discloses be not provided with magnetic mechanism at doctor-bar 4, consequently doctor-bar 4 can scrape down iron fillings fast, and iron fillings can glue on cylinder 1 surface under the attraction of magnet.

Specifically, the outer surface of the roller 1 is smooth, the roller 1 is a stainless steel cylinder, and the roller 1 rolls continuously in operation, namely clockwise in fig. 1.

Specifically, the scraping blade 4 is tightly attached to the surface of the roller to scrape off the coating on the surface of the roller 1, the scraping blade is used for scraping off iron filings and other substances, and the scraping blade 4 is usually a blade or a scraper.

Specifically, the chute 5 is located above the collecting tank 6, which mainly functions to collect iron-containing materials or iron powder, and the mounting position of the chute is to be capable of just receiving the iron chips scraped by the scraping blade 4.

In particular, the conveyor belt 7 is a rolling crawler belt for conveying the powder to other places, and can also be a collecting barrel or other collecting devices.

The utility model discloses in not drawing the fixed establishment of whole device, because of the relatively good realization of fixed establishment.

The utility model discloses an implement the step and do, constantly fall out the lithium manganate powder in the hourglass material mouth 3, the powder falls on 1 surfaces of cylinder, because there is magnet mechanism inside cylinder 1, so materials such as iron fillings can adsorb on 1 surfaces of cylinder, along with 1 rolls of cylinder, the lithium manganate powder drops on the conveyer belt under the action of gravity, and materials such as iron fillings roll doctor-bar department and drop to the collecting tank in, realize the deironing, circulate always and can realize the deironing effect.

Referring to fig. 2, a difference between the second embodiment and the first embodiment is that the magnetic mechanism 2 is implemented in a battery-induced manner to generate magnetism, which is more costly, but can effectively adjust the magnetic force according to the blanking speed to achieve more ideal iron removal.

Accordingly, the magnetic size can be adjusted by combining the permanent magnet and the coil to generate magnetism, so that the cost in the use process is reduced, and compared with the cost of adopting the permanent magnet, the cost is lower.

Like figure 3, for embodiment three, its mode is the stack combination formula, and the deironing in-process, if under the circumstances that speed is very fast, have unnecessary useful material to fall into to collecting groove, need go on again to the material that falls into, this embodiment improves the fineness of deironing through the form that sets up many sets of devices, like figure 3, the material of scraping out of hanging piece 4 at upper portion, deironing once is being carried out, and then realized more going on deironing effect, this is better to the powder effect that the iron content is higher.

The above disclosure is only a preferred embodiment of the present invention, and certainly should not be taken as limiting the scope of the invention, which is defined by the claims and their equivalents.
